Ductless mini-split systems provide an energy efficient, flexible way to heat and cool individual rooms or your entire home without relying on ductwork. At Althoff Home Services, we install, repair, and maintain ductless systems for homeowners in Crystal Lake, Hillside, and the surrounding Chicago suburbs, delivering personalized comfort right where you need it.
Whether you are replacing inefficient window units, finishing a basement, or supplementing comfort in a new room addition, ductless systems offer an adaptable heating and cooling solution. Our team takes the time to understand your home’s layout, providing thoughtful recommendations, clear communication, and expert installation.
Connect multiple sleek indoor air handlers to a single outdoor unit, allowing independent temperature control in different areas of your home.
Ideal for sunrooms, home additions, finished basements, or older homes where installing traditional ductwork is impractical or impossible.
Precision troubleshooting, filter cleaning, and coil maintenance to keep your mini-split running quietly and efficiently year after year.
Ductless systems deliver targeted heating and cooling through a small conduit that connects an outdoor compressor to indoor wall-mounted air handlers. Because conditioned air is delivered directly into the room, these systems eliminate the energy loss often associated with leaking ductwork.
Independently adjust temperatures in specific rooms to keep everyone comfortable and avoid heating or cooling empty spaces.
Without ductwork to leak conditioned air, mini-splits deliver higher efficiency that often translates directly to lower utility bills.
Built-in multi-stage filtration and active dehumidification remove dust, allergens, and excess moisture from your air.
